Notes on data changes

Here we list notes explaining important emissions changes for the country. ’' means that the following text only applies to the TP time series, while  means that it only applies to the CR scenario. Otherwise the note applies to both scenarios.

• We have added country reported data from China’s BUR3 and NC4 and created an independent CR scenario which differs from the TP scenario for most sectors and gases.
• HFCs and PFCs data have been added to the TP scenario from country reported as EDGAR has no HFCs and PFCs data for Hong Kong.
• Changes in sectors 4 and 5 are due to the removal of FAOSTAT data (CR (5 only), TP).

Changes by sector and gas

For each scenario and time frame the changes are displayed for all individual sectors and all individual gases. In the sector plot we use aggregate Kyoto GHGs in AR6GWP100. In the gas plot we usenational total emissions without LULUCF. ## country reported scenario
